I was a C++ programmer in a past life and I sorta like it. C++ and JIRA seem to have the same philosophy with respect to choosing which features to admit: "yes". The idea is that by supporting the largest number of features possible, they'll surely build something that everyone likes because it will tick everyone's boxes. What people frequently fail to realize is that the absence of misfeatures or redundant features is an important feature in and of itself. Moreover, the more features you support, the harder it is to control for quality.
